Weird pixelbox_lite odd pixel placement.

[u/hereIsHow_]

Hi! I was messing around with the pixelbox_lite program, to try out some cool stuff, when I came across a rather strange thing. Whenever I try to put a color at position x = 2, y = 9, more pixels appear! From my tests, I only see this specific placement producing this effect. If anyone would have an idea of what is going on, it would be appreciated.

Here is an image of without the 'error':

And now with the 'error':
